Hover Caption tute + added xml fed text?

Hi guys, long time lurker and not posted recently. My bad.

I’ve searched quite a bit to no avail, wondered if anyone could help with my issue.

I need to create the result of the Hover Caption tute, on Kirupa, with XML fed text rather than hard-coded text.

I know the XML tutes exist but I cannot seem to make the literal connection between the XML tutes and the hover caption one - so if anyone could actually show me how to create this modification it would be ace!
